Hey, everyone. Let's take a look at this question together. Classical arrangement in muscles is important. Why is it? Answer choice? A it is correlated to the force generated by a muscle and affects the muscles range of motion. Answer choice B it gives the muscles an additional way to generate more. A TP answer choice C it provides a way for muscles to compensate for additional stress that they may receive or answer. Choice D it limits the range of motion of muscles. Let's work this problem out together to try to figure out which of the following answer choices best explains why fasical arrangement in muscles is important. So in order to solve this question, we have to recall what we have learned about fascicles, specifically fasical arrangement in muscles. And we can recall that the term fascicle refers to a bundle of muscle fibers. And those fascicles are covered by a layer of connective tissue called peres. And we know that the f have various arrangements, each with a specific range of motion of which those various arrangements include circular convergent, fusiform, parallel, multi pennate, bi pennate and unipennate. And since each fascicle has a various arrangement with a specific range of motion. For each arrangement, f arrangement in muscles is important since it is correlated to the force generated by a muscle and affects the muscles range of motion. Since each arrangement is correlated to that force resulting in that specific range of motion. So answer choice A is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
